The earphones feature SnugFit earbuds for superior noise isolation, an inline remote with a mic for hands-free phone conversations, and volume control when plugged into your iPad, iPhone, or portable MP3 player. Quality, High Definition Audio Featuring single-balanced armature technology for professional-sounding audio, the Ultra earphones deliver professional-quality sound. The comfortable earbuds isolate out external noise, while the unique cord design prevents friction-related noise from interrupting your audio experience. In order to take advantage of the noise isolation and high quality audio these earphones are capable of, make sure to select the best fitting silicone ear tip for your ears and place them inside your ear canal for a tight seal.
